The invention discloses a nickel-copper-based diamond composite material and an electron beam additive manufacturing process and application thereof. According to the method, nickel-copper-based binding phase powder and diamond powder are mixed and then formed through a powder bed powder laying type electron beam additive manufacturing process, and the nickel-copper-based diamond composite material is obtained. The preparation method of the diamond composite material is expanded, the near-net forming of the diamond composite material is realized, the subsequent processing cost of the diamond composite material is reduced, and the production period is shortened. And meanwhile, the method has high process stability and is suitable for being applied to rapidly and stably preparing drilling tools, grinding tools, tools, molds and other diamond tools with specific complex configurations. 本发明公开了一种镍铜基金刚石复合材料及其电子束增材制造工艺与应用。该方法是将镍铜基粘结相粉末和金刚石粉末混合后通过粉床铺粉式电子束增材制造工艺成形，即得。本发明扩展了金刚石复合材料的制备方法，实现了金刚石复合材料的近净成形，减少了金刚石复合材料的后续加工成
